On or about Tuesday, Nov. 17 between 9 p.m. and 5 a.m., Dulles Corridor Metrorail Project crews will close the right lanes of Saarinen Circle coming into the airport from the westbound Dulles International Airport Access Highway (DIAAH) for overhead sign installation. The left through lane will remain open. Access to the terminal and the Hourly/Daily Parking Lot will be maintained; however, complete stoppages of up to 20 minutes will occur after 1 a.m. just east of the work areas the while sign is installed.

Flaggers will be in place to direct traffic as needed, and police will be present. Drivers should exercise caution, pay attention to barriers and signage, and obey all police and flagger instructions.
